Patented Apr, 3, 1945 MA NIFOLDING ASSEMBLY Alfred E. Vickery, Bridgeport, Conn., aslignor to Remington Rand Inc., Buil'alo, N. 1., a corporation of Delaware Application December 28, 1943. Serial No, 515,911 2 Claims. (01. 282-24) This invention relates to improvements in manifolding assemblies where a plurality of record and transfer leaves are secured together in registering relation for producing multiple copies of arecord made on the top or cover sheet.

The invention comprehends the provision of a plurality of record leaves and transfer leaves superimposed in alternate coincident relation having the top and bottom leaves providing cover leaves for the assembly, one of which is provided with adhesive securing means operable in cooperation with offset strip portions on each intermediate r remaining leaf to secure all of the leaves to the cover leaf carrying the adhesive in a manner that will enable detachment of the sheets from their connected relation in the pack without mutilation.

The invention provides for the recessing of the leaves along one margin in providing the offset securing strip sections which cooperate with a cover leaf in securing a group of leaves together in a united assembly that eliminates the application of adhesive to all but one of the leaves prior to the assembly of a group of leaves in manifold-- ing relation.

The manifolding assembly of this invention eliminates extra thickness caused by thebuildup of the adhesive with the leaves at the positions where they are bound together, thereby avoiding difliculties experienced with other types of manifolding assemblies when using them with bookkeeping machines.

The invention also comprehends the provision of a manifold assembly formed of multiple manifolding units having the sheets of each unit united together in unit form by means of ofiset strip portions formed by offset recesses in the margins of several sheets secured to a cover sheet with delineated adhesive on the margin thereof. All of the recessed sheets are secured to the cover sheet by means of the adhesive engaging the offset securing strip section's, while registering recesses in the margin of the sheets enable the delineated adhesive area on the cover sheet of one assembled unit to be detachably secured to the cover sheet of another assembled unit in order that twoor more units may be readily united in manifolding relation and arranged for subsequent detachment of each unit from the other without affecting the attachment of the leaves in the unit.

The invention further comprehends the provision of a manifolding assembly wherein the formation of the attaching strip section onone margin by the recessing of the margin of each sheet can be limited to a rather narrow marginal section of each sheet while at the same time obtaining efficient results in the mounting of the sheet in assembled manifolding relation with the structure of the sheets so arranged that adhesive need be applied to only one sheet prior to assembly in order to detachably unite all of the sheets or leaves to the one carrying the adhesive in a delineated area. In the drawings:

Fig. 1 is a partially diagrammatic view in perspective, showing the sheets of the manifolding assembly arranged in their order of assembly but in spaced disassembled relation.

Fig. 2 is an enlarged fragmentary elevation of an assembled group of intermediate leaves and a cover leaf having delineated adhesive areas showing how the adhesive areas cooperate with the securing strip portions of intermediate leaves in forming an assembled unit.

Fig. 3 is a view similar to Fig. 1 illustrating two manifolding assemblies in perspective and fragmentary partially diagrammatic illustration showing how the leaves of each unit may be assembled to one cover leaf by means of adhesive thereon and two units assembled by means of adhesive on one cover leaf engaging and securing another cover leaf thereto.

Fig. 4 shows in diagrammatic disassembled perspective, a fragmentary portion of one corner of a plurality of, leaves having circular perforations varying progressively in size in the respective leaves in order to present securing strip portions to a cover leaf provided with a delineated adhesive area.

Fig. 5 shows the intermediate sheets as illustrated in Fig. 4 arranged in superimposed relation in elevation for illustrating the arrangement of the marginal securing strip sections on each sheet that face the adhesive area on the cover leaf.

Figs. 6 and 7 are similar to Figs. 4 and.5, but illustrate how securing strip sections may be formed by providing V-shaped notches in the edges of intermediate leaves of varying size to provide the securing strip sections.

Fig. 8 illustrates how apertures of uniform size may be provided in a plurality of leaves in ofiset relation to provide the securing strips, the figure showing a fragmentary elevation of one comer of an assembled group of leaves.

A folded sheet is indicated at l in Fig. 1 having the inner face of the rear section thereof provided with a coating of hectograph ink indicated at 2. Smudging of this hectograph ink on the rear face of the front sheet section is eliminated in the normal handling of the sheet prior to typing on the front section by means of a protective tissue 3 inserted between the front and back sections of folded sheet I, as shown. A structure of this type is well-'known in the art and is usually referred to as a master sheet." It is used in gelatine and spirit duplicating machines for copy reproducing purposes. The outside face of either the front or back sections of folded sheet I may be written or typed on in producing a hectograph master copy on the front section of the folded sheet for use in either the spirit or gelatine type duplicating process. The manner of typing this master is well known in the art and forms no part of the present invention.

In using these hectograph master sheets it is frequently desired at the time of preparing the master copy also to prepare one or more carbon copies of the information written upon the master sheet. In the form illustrated in Fig. 1 the.

face of the front section of the folded sheet I is adapted to be typed or otherwise written upon in providing the master copy and a plurality of additional sheets composed of record sheets or leaves 4, 5 and 6 are provided with intermediate transfer leaves 1 arranged therebetween. Leaf 6 will form a cover sheet while leaves 4, 5 and 'I will form a series of supplemental or intermediate sheets remaining between cover sheet 6 and folded sheet I forming a front cover for the assembly. Each of the remaining or intermediate leaves 4, 5 and 1 have one marginal portion recessed as indicated at 8. In Fig. 1 the recesses are shown in the upper margin of each of the intermediate leaves as being offset longitudinally of the margin. That is, the recessed portions of sheet 4 are offset to the right of the recessed portions of transfer leaf I immediately to the rear of folded sheet I while the transfer leaf 1 to the rear of sheet the right of those in sheet 4. From front to back of the series of sheets the offsetting of recesses 8 is progressively toward the right as illustrated in Fig. 1. Two sets of recesses are illustrated and it is to be understood that one, two or even 4 has the recesses offset to overlapping relation so that the strip sections 9 facing in one direction are exposed through the sheets to the rear as well as to the front of the assembled group of leaves or sheets. This makes it possible to use an adhesive coated area on either the front cover or the back cover. In the structure shown in Figs. l and 2 recesses 8 register so as to provide a section of adhesive III on rear cover leaf 6, that may be united to the rear upper marginal portion of folded sheet I so as to unite master sheet assembly I with the remaining record and transfer leaves to form a unit sheet assembly.

The assembly of the leaf by mean's of adhesive and marginal strip portions 9 will firmly secure the record leaves and transfer sheets in coincidental superimposed relation in a manner so that all of the sheets or leaves are secured to the back cover independently of the others. The size of strip portions 9 is such that the attachment of each sheet to the back cover will provide for the convenient detachment of each sheet from the assembly when desired without unduly mutilating any leaf that is detached. Further, by utilizing longitudinally extendin rectangular recesses in the marginal portion of the intermediate or supplemental leaves, it is apparent that 40 or face toward sheet I2. Sheets I2 and I3 are more of these offset sets of recesses may be formed in the margin of any manifold assembly constructed according to*this invention for cooperation in securing the sheets together in superimposed coincident relation.

By this ofiset arrangement of recesses 8 a marginal strip portion forming a securing section 9 is provided on each intermediate sheet at opposite ends of the recess arranged so that these marginal portions 9 on all of the sheets are arranged in offset relation longitudinally along the margin. These securing sections 9 in the structure shown in Figs. so that one set of securing sections at one end of recesses 8 face rear cover leaf 6 while the securing sections 9 at the opposite ends of recesses 8 face toward the front of the assembly.

A delineated area of adhesive I0 is applied to the inner rear marginal portion of record leaf 6 in registry with recesses 8 as clearly shown in Fig. 2. The delineated'area of adhesive is spaced inwardly from the edge of sheet 6 as indicated at II so that when the sheets are united in assembled form the pressing of the sheets together will not squeeze the adhesive outwardly beyond the edge of the sheet.

1 and 2 are arrangedof uniform size and are superimposed in coincident relation with a protective tissue sheet I4 of smaller size than sheets I2 and I3 interposed over the hectograph coating to protect it during handling in advance of the production of the master copy in a mannerwell known 'in the art. This master copy unit is assembled by having delineated adhesive areas I5 of annular or circular shape provided thereon in spaced relation along one marginal portion and spaced inwardly of the edges. Protective sheet I4 has the upper edge thereof-I constructed with a recessed marginal section extending entirely across the up.- per edge of the sheet'in order that it will only overlap about half of the adhesive areas I5 as illustrated in Fig. 3 when properly positioned in its assembled relation with sheets I2 and I3. Sheet I2 will thereby be secured to sheet I3 by the upper half of the adhesive areas I5. As a result each of the sheets or leaves I2 and I4 is arranged with offset adjacent marginal strip por- It will be noted that an of the recesses a I while being offset in successive leaves from the front to the rear of the assembled group are in tions in registry with adhesive areas I5 in the same manner as sections 9 in Figs. land 2. In this way sheets I2, I3 and I4 are assembled together to form a manifolding assembly unit.

Another unit is comprised of front and .back cover sheets I6 and II with the remaining intermediate leaves III arranged so that alternate leaves are transfer leaves for making carbon copies. The intermediate leaves I8 are provided with progressively offset recesses I9 constructed as described in connection with Figs. 1 and 2 to provide securing strip sections facing rearwardly through the registering recesses I9 for registry with delineated areas of adhesive 20 on ,cover I1 a manifolding assembly for thereby securing all of the intermediate and cover sheets is, I! and it together in unit form. Each of the sheets is secured to the rear cover sheet I! by means of theoffset securing strip portions adjacent each recess IS. The marginal portion of front cover I 6 has a strip section exposed through recesses 19 for registry with adhesive area 20.

This unit including sheets l6, l7 and I8, is constructed so that cover 16 and each intermediate leaf i 8 is provided with registering apertures or recesses 2| in the upper margin also registering with a delineated area of adhesive on rear cover H, indicated at 22. In the assembled superimposed coincident relation of the sheets in this unit it will be seen that the adhesive of area 22 will be exposed through recesses in order to provide for the attachment of the unit to another similar unit, such as the one composed of sheets l2. l3 and 14. In the arrangement illustrated in Fig. 3 the adhesive area 22 will engage through recesses 2| with the rear upper margin of sheet [3 for adhesive attachment to therear face thereof to thereby secure the two independently assembled sheet units together at spaced positions along one margin in superimposed relation.

These units may then be used to produce an original copy on the top or front sheet i2 which will be reproduced on all of the record sheets in the other unit to provide carbon copies thereof by means of the transfer sheets or leaves, in a manner well known in the art. When the record on sheet I2 has been'completed, the two units may be separated because the strip attachment of area 22 of the unit including cover H with the unit including cover leaf i3 can be readily detached without mutilating the leaves and without disassembling the group of leaves in each unit because of the limited character of attachment obtained by the delineated adhesive areas.

Figs. 4 and 5 illustrate how the attaching strips may be provided on one marginal portion-of a group of sheets for assembling them to one cover sheet by forming the sheet margins with circular openings or apertures 23. The apertures in each successive sheet are progressively smaller in size beginning next to the rear coversheet having a circular area of adhesive 26. The securing strip sections are of annular form as indicated in Fig. 5 at 25. The manner of assembly and operation of these strip sections is the same as in connection with the disclosures in Figs. 1 to 3. This construction of securing strip structure may be used for securing the sheets of a unit together instead of the structure shown in Figs. 1 to 3. It may also be employed where two or more units are united together, as described in connection with Fi 3.

Figs. 6 and 7 illustrate a plurality of sheets 26 formed with V-shaped notches of progressively varying size opening through the upper edge of the sheet in registry and providing the securing strip sections 21 facing the rear cover sheet having a triangular area of adhesive 28. This adhesive area 28 cooperates with V-shaped strip sections 21 to secure all of these superimposed coincident sheets in assembled relation to the rear cover.

Fig. 8 illustrates how circular apertures 29 of uniform size may be formed in a series of sheets in overlapping ofiset relation when assembled thereby providing a plurality of securing strips 30 in a form simulating a crescent, and facing in one direction through the registering portions of the openings for engagement with a delineated area of adhesive on either a front or rear cover leaf.

It will be understood that two individually assembled units may be united together b having a single area of adhesive operate, not onl to secure the leaves of one unit in assembled relation with one of the covers, but also to form an openingthrough the aligned recesses adjacent the securing strips so that strips of adhesive exposed through the opening may be attachedto the cover leaf of another unit for assembling two or more units; 7

The spacing of the adhesive areas slightly inward from the edge of the sheet overcomes a substantial disadvantage heretofore experienced with many manifolding assemblies secured together by adhesive along the edges due to the sheet area having the adhesive thicker than the composite sheet thickness. This increased thickness in adhesive areas causes interference in the feeding of the manifolding set through bookkeeping and accounting machines during the printing operation for recording the desired information on the leaves. The structure of the securing means of the present invention eliminates-the build-up caused by the adhesive at the point where the sheets are united together due to the fact that the recessing of the sheets in the formation of the plurality of offset securing strip sections provides for compensation of the build-up caused by the adhesive so that the resultant leaf assembly is of no greater thickness in cross-section at the points of adhesive attachment than throughout other portions of the assembly.

A particular advantage of the present invention resides in requiring application of the adhesive to only one sheet in order to assemble an entire groupof sheets in any one unit. The invention further provides that adhesive on the 40 same sheet also operates to secure another unit thereto so that two sheet units consisting of a substantial number of sheets may be secured togather in superimposed manifolding relation by only having adhesive on two sheets of the entire assembly of two units, the adhesive being applied only to one of the cover sheets of each unit. This eliminates many disadvantages in making manifold assemblies caused from the difficulty in handling and applying the adhesive necessary to unite the sheets in group form. A further advantage of the invention is in controlling thev area attached 'by adhesive on'each sheet to limit the attachment to such an extent that the desired amount of attachment can be obtained to readily hold the sheets in manifold relation, while they are being typed or printed,

and yet, provide an assembly whereby the sheets may be readily detached-without mutilating the sheet. The invention further facilitates economy by having the apertures offset longitudinally along one margin whereby they may be maintained of uniform depth as in the structure shown in Figs. 1 to 3, for example. This provides for using only a limited portion of the margin of all the leaves in providing the detachable securing means uniting sheets in assembled groups.

With the present invention a manifold assembly can be produced having a master sheet and any desired number of carbon copies, so that the master sheet can be used thereafter for the reproduction of additional copies by the gelatine or spirit duplicator processes. The unit structure of the assembly is arranged to provide for the detachment of the master hectograph unit,

whether in the form of the folded sheet i or the separate'sheet structure l2, l3 and I4, from other leaf units composed of a series of alternate record and transfer sheets on which carbon copies of the record are produced in making the master sheet.-

It will be understood that in making a manifold assembly having two units, the adhesive may be applied to opposite faces of a centrally disposed cover sheet for attachment of the sheets in both units to opposite faces thereof.

The invention claimed is:

1. A manifolding assembly comprising a plu-' ra-lity of record and transfer leaves overlapping each other in coincident manifolding relation, one of said leaves forming a cover leaf and the remaining leaves being arranged in superimposed coincident relation on said cover leaf with uni form sized recess formed in one margin of each remaining leaf in overlapping offset relation to corresponding recesses in adjacent leaves, each recess extending inwardly from the edge of the leaf a uniform distance and being offset longitudinally along said margin to form a plurality of strip sections offset longitudinally along said margin perpendicular to the edge of said strip sections on each remaining leaf facing in opposite directions, one set facing said cover leaf, and a delineated area of adhesive on the margin of said cover leaf spaced inwardly from the edge of said leaf and overlying all of said strip sections for securing all of said remaining leaves to said cover leaf by said strip sections.

2. A manifolding assembly comprising a pair of assembled leafunits, each unit having a pair of cover leaves and a plurality of supplemental leaves each, formed with two series of openings,

' one series of openings being in aligned registering both series of openings operable to adhesivelysecure all of said strip sections between said cover leaves to attach all of said supplemental leaves and said cover leaves through one series of openings together in unit form and operable through the aligned series of openings to secure another unit thereto and forming a manifold assembly adapted to have the units detached without disturbing the leaf attachment in a unit.
